摘　　要：电源电压随CMOS工艺节点微缩而降低,使模拟电路设计面临严峻挑战。CMOS反相器因其结构简单,在给定电流下可获得相对高的线性跨导,适合于作为低压高能效模拟电路的构造单元。文章分析了低压高能效模拟单元电路,包括运算跨导放大器、高增益离散积分器、gm-C滤波器等,展望了基于CMOS反相器的低压高能效模拟电路,如TIQ比较器、Δ-Σ调制器、环形振荡器与环形放大器、光链中的跨阻放大器与VCSEL驱动器、射频电路中的乘法器、合成器、有源电感等未来的应用前景。The power supply reduction with CMOS technology node scaling poses great challenges to the design of analog circuits.The simple structure of its inverter and relatively higher linear transconductance at a given current make CMOS a suitable building block for low-voltage,energy-efficient analog circuits.This paper analyzed the low-voltage,energy-efficient analog circuits,including operational transconductance amplifiers,high-gain discrete integrators,gm-C filters,etc.and looked to the future of low-voltage,energy-efficient analog circuits based on CMOS inverters,such as TIQ comparators,Δ-Σmodulators,ring oscillators,ring amplifiers,transimpedance amplifiers and VCSEL drivers in optical chains,and multipliers,synthesizers,active inductors in RF circuits,etc.
